Antibiotic Susceptibility and Clarithromycin Resistance Determinants in Helicobacter pylori in the Northeast of Spain: A One-Year Prospective Study [PDF]
Antibiotics, 2023 Helicobacter pylori is one of the most widespread infections, and it is reaching alarming resistance levels worldwide. The recommended first-line empirical treatment differs according to the local rate of clarithromycin resistance.

Pathophysiology of Antibiotic Resistance: Clarithromycin [PDF]
Canadian Journal of Gastroenterology & Hepatology, 2000 Resistance ofHelicobacter pylorito antibiotics ranges from 3% to 10% and may exceed these levels in some countries. The pathophysiology of clarithromycin resistance is reviewed, including the mode of action by which the antibiotic inhibits protein synthesis and the mechanism of resistance, which involves a mutation at position 2142 or 2143 in the V ...

Molecular Characterization of Clarithromycin Resistance in Helicobacter pylori Strains. [PDF]
Turk J Gastroenterol, 2023 Background: The purpose of this study was to determine the antimicrobial status of stocked clinical Helicobacter pylori isolates by using antibiotic gradient test and subsequently identify the mutations that cause clarithromycin resistance by DNA sequencing.

Genetic Evolution of Mycobacterium abscessus Conferring Clarithromycin Resistance during Long-Term Antibiotic Therapy [PDF]
Canadian Respiratory Journal, 2020 Objectives. Clarithromycin is recommended as the core agent for treating M. abscessus infections, which usually calls for at least one year of treatment course, facilitating the development of resistance.

Early genetic diagnosis of clarithromycin resistance in Helicobacter pylori. [PDF]
World J Gastroenterol, 2021 The drug resistance rate of clinical Helicobacter pylori (H. pylori) isolates has increased. However, the mechanism of drug resistance remains unclear. In this study, drug-resistant H. pylori strains were isolated from different areas and different populations of Chinese for genomic analysis.To investigate drug-resistant genes in H. pylori and find the

Clarithromycin Resistance in Helicobacter Pylori
Central Asian Journal of Medical Sciences, 2016 Objectives: Eradication rates of Helicobacter pylori with standard triple therapy are disappointing in studies from several countries. The main reason for failure was found to be bacterial resistance to one of the most commonly used antibiotics ...

Mycobacterium avium strains resistant to clarithromycin and azithromycin [PDF]
Antimicrobial Agents and Chemotherapy, 1993 Mycobacterium avium strains susceptible to clarithromycin and azithromycin contain mutants resistant to these macrolides with a frequency of 1.1 x 10(-10) to 1.2 x 10(-6). Cross-resistance between clarithromycin and azithromycin was demonstrated with mutants selected in the laboratory as well as with resistant strains isolated from patients.
